The Polk Audio Monitor XT90 height speakers are engineered to unlock the full potential of multi-dimensional audio formats like Dolby Atmos, DTS:X, and Auro-3D. Whether placed seamlessly atop your Monitor XT bookshelf or floor-standing speakers to reflect sound off the ceiling, or easily wall-mounted to serve as directional height channels, the XT90 envelops you in a highly realistic 3D soundfield. Featuring a premium 4-inch dynamically balanced woofer and timbre-matched perfectly with the entire Monitor XT family, it ensures that overhead effects—from roaring planes to subtle atmospheric rain—are reproduced with lifelike clarity and striking cinematic impact.
